| Audio Research VT100 MK1 and LS15 HELP!!! V1 and V2 are typically the gain stage tubes. | |
| Audio Research VT100 MK1 and LS15 HELP!!! You could, but the other tube could go bad at any time since you don't know it's age. When you replace the pair they will both be strong tubes. | |
| Audio Research VT100 MK1 and LS15 HELP!!! Preamp tubes are replaced in pairs. Two in the front, two in back. If the pair that supplies gain to the preamp are bad or weak, then there's not enough juice to drive the amp.Look at the manual and identify which tube is bad...V1 V2 V3 V4 | |
| Audio Research VT100 MK1 and LS15 HELP!!! No need to bias the preamp tubes. They're set at the factory.If there's a short or other issue in the circuit the tube could blow again. It would be great if you only need a new tube. | |
| Audio Research VT100 MK1 and LS15 HELP!!! Yes. Do you have a spare of the same tube type? If you replace the tube and it sparks again, you need service. | |
| Audio Research VT100 MK1 and LS15 HELP!!! Have you been interrupting power to the preamp, eg, pulling out the AC cable, powering the preamp or amp on, off quickly?There is a safety mode on the preamp if power is interrupted.http://vpiforum.com/viewtopic.php?f=7&t=8590 | |
| Audio Research VT100 MK1 and LS15 HELP!!! Jumpers are used in the amp XLR inputs when you are using RCA cables. But you're using XLR between amp and preamp, correct? | |
| Audio Research VT100 MK1 and LS15 HELP!!! Where did the Gold Phantom come from? What kind of inputs does it have?Can you repeat Jea's test but this time use the 4 ohm taps. The bass on your speakers is about 4 ohms. | |
| Fedex issues You can complain to FedEx about the driver forging your signature. They take Signature Required seriously. I complained by phone about a driver who didn't show up two days in a row but said he did and nobody was home. I told them I was sitting in ... | |
| Audio Research VT100 MK1 and LS15 HELP!!! Do you have any other sources? TV, turntable, tuner. Maybe the Mac 1500 has a preamp output you can plug into the amp. | |
| Audio Research VT100 MK1 and LS15 HELP!!! A CD is always a good reference to use when testing a system. | |
| Audio Research VT100 MK1 and LS15 HELP!!! The only difference is the dac most likely has a higher gain than your CDP.That doesn't explain why you have poor bass response. | |
| Audio Research VT100 MK1 and LS15 HELP!!! No, I don't believe it would. I'll assume he was using balanced connections from dac to ARC preamp. That would provide higher gain to the preamp and then the amp.RCA out of your CD into the proper RCA preamp input should result in good sonics at a... | |
| Audio Research VT100 MK1 and LS15 HELP!!! OK, that's a good start to troubleshooting, but since the Mac is a receiver you've removed both the amp and preamp from the system.Have you re-seated all the tubes in both components? Gently wiggle them out (not all the way) and push them back int... | |
| Audio Research VT100 MK1 and LS15 HELP!!! There’s nothing wrong with your speakers. I’ve heard the R900 with a 30W tube amp and it was a very pleasant listening experience. The R series is the entry-level for KEF, so there is some cost cutting to the cabinets and bracing, but not the driv... |
